Abstract

Current sensing is an essential part of a wide range of applications from low-power handheld consumer products to high-power electro-mobility drivetrains. The state of charge in a battery and its load monitoring, the control of an electromotor, a power converter, or a biosensor, all have specific demands when it comes to dynamic range, precision, speed, isolation, size, and cost. This chapter provides an overview of the applications and principles of operation for the two main current sensing approaches: contacted (shunt-based) and contactless or isolated (magnetic or coil based).

Keywords
